At Veritas infosystems we highlight some alternative development approaches for incrementally modernizing legacy systems, including consideration of the advantages and disadvantages of each approach. These development alternatives can be mapped against the peculiarities of a particular modernization effort to recommend an appropriate approach. We realize that there is no single solution for all customers. Each situation is unique due to the variety in both their system and business environments.
Because of the large capital investment in Legacy systems and potential disruption of system support, it is preferable to find a satisfactory migration path from the Legacy system environment to the newer client server environment.
Many automation needs were met by existing Legacy systems developed in the early 90's.
With the advent of Internet technologies business practices are changing and must be supported by new technologies.
